Spanish Patent 287,924

This 1963 Triplex design looks like a cheap and nasty derivative of the Campagnolo Gran Sport. It appears to use its fair share of pressed steel, and has opted for hex head bolts rather than the more deluxe Allen key variety.

Strangely the pulley cage pivot is slightly offset from the centre line of the two pulleys. Perhaps this is an entertaining touch of Daliesque surrealism.
